PC1066 RDRAM vs. DDR SDRAM

Posted by CmdrTaco on from the tweaking-something-out dept.

Brad wrote into send us his "Comparison of PC1066 RDRAM vs DDR SDRAM. Quote - RDRAM is considerably more expensive that DDR SDRAM, and up until now the 100MHz PC800 specification didn't do well in comparison. Just recently 133MHz PC1066 was launched, and is now officially supported by the new Intel P4 and the Intel 850E core logic chipset, but this time promises to bring memory performance to the next level."

    Intel's i850 does not support PC1066 officially, and parts of that speed have only been validated since the release of i850E. Officially, the chipset simply supports a FSB that would complement that speed, if the two busses ran synchronously. Seen here:

    That said, PC1066 has been tested before (can't find the article at Ace's Hardware), and the bandwidth of DRDRAM appears to compensate quite nicely for the P4's generally lousy architecture, as does its increased cache size (now 512k L2).
